      Gastropods, or snails, are common fossils thanks to their strong, easily preserved external shells. Quite a few fossil gastropods are traded commercially, including members of the genus Turritella. This particular genus first appears in the fossil record during the mid Cretaceous and includes many species still alive today. If you know where to look, you.

However, it is not a legal authority for statutory or regulatory purposes. While every effort has been made to provide the most reliable and up-to-date information available, ultimate legal requirements with respect to species are contained in Biological classification: Class. Overview. The Class: Gastropoda includes most molluscs, with perh existing species fossil forms. Generally, the gastropods have an asymmetrically spiral shell, which functions as a portable retreat. Their body consists of a head, foot, visceral hump, and mantle.

Members of the genus first appeared during the Oligocene. Like most land snails, Helix species are hermaphroditic, and like other helicids a courting pair will impale each other with Class: Gastropoda. You searched for: gastropod fossils.

The shell of Trochonema consists of a series of turretlike whorls, each ornamented by slight lines. The aperture is large.
